Low NOx combustion system was developed forgas firing. Most overseas gas turbines are required for firing oil asbackup fuel. Low NOx combustion systems for dual fuel firing arerequired. Lean fuel premix combustion is used for gas and leanfuel diffusion combustion for oil. Basic tests were conducted tooptimize a premix fuel-air nozzle and performance was verified inhigh-pressure combustion tests. Commissioning tests on gas andoil burning were completed at overseas power plants.
